Figure 2: Conformational changes in the active site accompany HDV ribozyme cleavage. a, 3.4 Å experimental electron-density map of the wild-type precursor HDV ribozyme (1 ) superimposed on the refined wild-type structure model (magenta) and that of the C75U mutant (grey). b, Backbone alignment of the precursor (magenta) and product (grey) ribozyme structures. c, Stereo view of the aligned active sites of the precursor (coloured) and product (grey) ribozyme structures. Conformational changes were modelled using the C75U mutant ribozyme structure, shown by arrows.
